Investing Money for Grandchildren Without Parents' Access: The Ultimate Guide for Grandparents

Many grandparents want to make their grandchildren’s start in life as easy as possible. A financial cushion gives the younger generation freedom, a great deal of security, and tremendous opportunities—whether for a driver’s license, vocational training, their first car, or their first apartment. But what’s the best way to go about it? Cash gifts are often quickly spent on toys or other consumer goods. True help getting started requires foresight.

If you make a plan early on, you’ll benefit from the power of compound interest thanks to long investment horizons. That way, even small monthly amounts can grow into a substantial nest egg over the years. In this guide, you’ll learn everything you need to know about investing wisely—from traditional savings accounts and modern ETFs to how grandparents can manage their capital safely and effectively.

Why Cash Alone Is Often Not Enough for Grandchildren

Birthdays or Christmas are great occasions to give an envelope full of cash—something that instantly makes a child’s eyes light up. Gifts like these are wonderful in the moment. But in the long run, your grandchild won’t be building up any wealth this way. In a regular checking account or a piggy bank, the money gradually loses value due to inflation. Its purchasing power dwindles year after year. What’s enough to buy a bike today might be worth only half as much in ten years.

A structured investment plan for grandchildren takes a different approach: It protects the assets from losing value and allows them to grow over the long term. Investing early gives the money one thing above all else—time. The longer the capital remains invested, the more the effect of compound interest can take hold and the higher the return can grow.

Here is a specific example to illustrate this:

Instead of just giving money occasionally, you can lay the foundation for your grandchild’s financial future with as little as 50 euros a month. If the contributions are invested in a globally diversified equity fund and generate an average long-term return of 6% per year*, the investment can grow to around 19,000 euros after 18 years. Of that amount, nearly 8,500 euros comes from interest and capital gains alone—an impressive example of how time and the power of compound interest work in your favor.

Investing Money Wisely for Your Grandchildren: What Matters?

Before you make your first contribution, it’s helpful to clearly define your goals. Are you looking for security, a high degree of flexibility, or maximum returns? Choosing the right savings options depends heavily on your priorities.

A structured approach will help you avoid common mistakes. Think carefully about the following in advance:

• Should the money be available at a specific time (for example, when the child reaches the age of majority) or for a specific purpose (such as college)?
• Would you like to transfer a fixed amount each month, or would you prefer to contribute irregular amounts on specific holidays?
• Do you want to retain control, or would you like to transfer ownership early on?

Investing money for grandchildren without parents having access to it—how is that possible?

One question our experts hear very often during consultations is: How can you invest money for grandchildren without their parents having access to it? Sometimes grandparents simply want to prevent the money they’ve painstakingly saved from being used for everyday household expenses or consumer spending when the family faces financial difficulties. Often, it’s also a matter of complex family structures, separations, or simply the desire to give a very private gift to a grandchild.

In general, an account or brokerage account in a child’s name can only be opened with the parents’ consent. Since minor children do not have full legal capacity, the parents with custody act as legal representatives. This means that, until the child reaches the age of majority, the parents have legal access to the assets held in the child’s name. They manage these assets in a fiduciary capacity.

If you want to retain full control over the assets, there are suitable solutions. One tried-and-true option is to set up the investment in your own name as a grandparent and stipulate in the contract that the assets will later benefit exclusively the grandchild.

Specialized providers such as Invest4Kids offer appropriate solutions for this purpose. In these arrangements, the grandparents remain the policyholders and continue to make investment decisions. Through a contractual provision—such as a contract in favor of a third party—the assets can be legally reserved for the grandchild. This ensures that the accumulated capital remains under the grandparents’ control until the agreed-upon transfer and is not accessible to the parents.

Invest wisely for your grandchildren without giving up access to your funds

If you choose a solution in which the parents have no access to the assets, in many cases you can even retain control beyond your grandchild’s 18th birthday. An important advantage of such arrangements is the so-called right of determination, which is also offered by Invest4Kids’ children’s savings plan.

With a traditional junior investment account, ownership of the account automatically transfers to the child upon reaching the age of majority. From that point on, the child can freely dispose of the entire balance. However, many grandparents would like the savings to be used later for specific purposes, such as education, college, a driver’s license, or a first apartment.

With a carefully designed insurance plan, you can build up assets for your grandchild and, at the same time, specify when the payout should occur. This way, you decide for yourself when the accumulated capital will be transferred to your grandchild.

The Big Decision: Checking Account or Brokerage Account?

Today, grandparents can choose from a wide range of options for investing money for their grandchildren. These can generally be divided into two categories: traditional savings accounts and capital market-based investments. Both have their own strengths and weaknesses—which option is right depends on personal goals and the investment horizon.

1. Traditional savings accounts: Safe, but usually unprofitable

For a long time, the savings account was the classic investment for grandchildren. For many grandparents, it was a tradition to open a savings account shortly after a grandchild’s birth, thereby laying the foundation for the grandchild’s financial future.

Even today, savings accounts and money market accounts are among the safest forms of investment. Balances in these accounts are protected by the statutory deposit insurance in the EU up to 100,000 euros per person per bank.

However, this security comes at a price: Savings accounts now pay virtually no interest, and even overnight or fixed-term deposit accounts often yield only minimal returns. Although a fixed-term deposit account offers a guaranteed interest rate for a fixed term, this is often not enough to offset inflation. As a result, the money saved loses purchasing power over time. For long-term wealth accumulation, traditional forms of saving are therefore often only of limited use.

2. The Portfolio: Opportunities in the Global Capital Markets

A securities account is held with a bank or broker and allows you to buy stocks, mutual funds, and ETFs. Investors who diversify their portfolios across the global stock market benefit from the growth of the global economy over the long term.

While short-term price fluctuations are to be expected, historically they have generally been offset over long investment horizons. For this reason, broadly diversified equity investments are considered a promising option for long-term wealth accumulation, particularly over an investment horizon of 15 years or more.

The ETF Savings Plan as a Modern Source of Returns

In recent years, an ETF savings plan has established itself as one of the most sensible ways to invest in the stock market consistently over the long term. ETFs (Exchange-Traded Funds) track major market indices such as the MSCI World. They automatically spread the risk across hundreds of companies worldwide. If one company goes bankrupt, the others offset the losses.

A savings plan like this is ideal for grandparents. It’s cost-effective, very transparent, and offers the potential for high returns over the long term. You can start with even small monthly contributions and adjust your payments at any time to fit your financial situation. There are generally no expensive commissions for active fund managers.

Note: An ETF savings plan in a brokerage account is a popular solution. For grandparents who also prioritize asset protection, control, and potential tax benefits, specialized insurance plans may be the better choice.

Open a brokerage account in the grandchild's name

If you decide to open the brokerage account directly in the child’s name, you’ll be able to take advantage of the child’s tax allowances. Children have their own flat-rate savings allowance of 1,000 euros per year (as of 2026). In addition, the basic tax exemption applies, meaning that very high gains can be realized without incurring immediate taxes.

The catch: As mentioned earlier, opening an account in the grandchild’s name requires the signature of the legal guardians. An account or brokerage account in the grandchild’s name may only be opened by the parents who have legal custody. The parents must provide proof of identity to the bank and have full authority to manage the account until the grandchild reaches the age of majority. Upon turning 18, the entire balance is then transferred to the grandchild without restriction.

Maintain a brokerage account in the grandparents' names

If you'd rather set the money aside in your own name, you can bypass parental permission entirely. You retain control. However, there are legal and tax implications you should be fully aware of beforehand:

• Taxes and Income: Income earned on an account in your name counts toward your own tax-exempt savings allowance. If you have already fully utilized this allowance through your own retirement savings or other investments, you must pay the flat-rate withholding tax on the earnings from the “grandchild money.”
• The Topic of Inheritance: In the event of your death, the balance in the account becomes part of your estate, unless otherwise specified in the contract. The money will then be divided among all legal heirs, and your grandchild may end up with nothing at all or receive only a small portion. A trust account requires very clear contractual documentation to ensure legal certainty in such cases.

That's why investing early is so important for grandchildren

Those who start building wealth early gain the greatest advantage: time. Even small monthly amounts can grow significantly over 15 or 18 years. If you start as soon as your grandchild is born, regular contributions of 25 or 50 euros a month can lay an important foundation for their financial future.

A well-structured plan is also worthwhile from a tax perspective. Grandparents may give their grandchildren up to 200,000 euros tax-free every ten years. For the vast majority of families, this tax-free allowance is more than sufficient. However, anyone wishing to transfer larger assets should spread the amounts out wisely over the years in order to make the best possible use of the tax-free allowances.

Important to know: For tax purposes, a gift is generally considered to have taken place only as of the date of the actual transfer. Anyone who accumulates assets in their own name over many years and then transfers them all at once at a later date should take potential tax implications into account.

A gift subject to a condition can help establish the purpose of the assets at an early stage. For example, it can be agreed that the money may be used exclusively for the grandchild’s education or college studies.

Benefits of Investing Without Third-Party Access

Why do many families look for ways to invest money for their grandchildren without allowing the parents to access it? Often, this isn’t a matter of a lack of trust, but rather of having clear rules and a clean separation of assets. When family structures are complex (such as in cases of parental separation or blended families), a strictly separate and contractually protected investment ensures peace of mind.

With specialized children's savings plans such as Invest4Kids, grandparents can act as the policyholders and structure the investment themselves. This ensures that the agreed-upon rights and control over the assets remain clearly defined.

A separate investment account can help clarify ownership and ensure that the saved funds are used for the grandchild in accordance with the grandparents' wishes.

Investing for Your Grandchildren: Setting Goals

Successful wealth building always starts with a clear goal in mind. What do you want to invest in for your grandchildren?

1. Short-term goals (0–3 years): A new bike for the commute to school, an ergonomic backpack, or a high-performance laptop for school. A simple demand deposit account is ideal for these purposes. Returns aren’t a factor here—the money just needs to be readily available.
2. Medium-term goals (3–10 years): An expensive driver's license or a year abroad in the United States. For larger goals in the future, a balanced mix of safe investments and income-oriented funds can be a wise choice.
3. Long-term savings goals (10–18+ years): An expensive college education in another city, furnishing your first apartment, or even saving for your child’s retirement. To achieve these goals, there’s no way around stocks, ETFs, and unit-linked retirement plans.

Statistics repeatedly show how sharply the cost of living is rising, especially for young adults in school. Having a financial cushion saved up early on is more valuable today than ever before. Grandparents who help out in this way take a huge burden off these young people’s shoulders.

Avoiding Common Mistakes When Saving Money

Even with a well-intentioned plan, mistakes can creep in. When saving for your grandchildren, it’s therefore worth keeping a few important points in mind and avoiding common mistakes:

• Starting way too late: Every month that money sits unused in a checking account costs you money due to inflation. Your purchasing power is eroding.
• Insist only on absolute safety: Those who rely exclusively on traditional savings vehicles out of fear of price fluctuations may be missing out on long-term growth opportunities. Fluctuations in the stock markets are a natural part of investing and tend to even out over very long time horizons.
• Ignoring or miscalculating costs: At first glance, a standard investment account often seems very affordable. However, every time you change your investment strategy, you’ll incur withholding taxes that can affect the future growth of your capital. A smart retirement plan allows you to reallocate your investments within the plan tax-free.
• Do not seek counseling: The world of finance is complex and confusing. The Invest4Kids team offers you expert advice—completely free of charge—to help you find the best financial plan for your family. Without expert knowledge, it’s easy to fall into costly tax traps.

Finding the Best Investment for Your Grandchildren

There is no single “perfect” solution that works the same way for every family. The choice of the best strategy should always be based on your individual needs. Do you want full control, significant tax benefits, and strong protection against changes in the law? If so, the Invest4Kids concept is often far superior to traditional investment accounts.

Your real benefits with Invest4Kids at a glance:

• The right to decide starting at age 18: You retain control, even after your grandchild turns 18. The funds are not immediately available to the child for any purpose, but can be used specifically to help achieve important life goals.
• Saving the conditions: This plan provides you with contractual protection against sudden changes in taxes or hidden fees. Your terms remain fixed.
• Smart Tax Benefits: A change in strategy (for example, switching from an ETF to a completely different market) does not trigger capital gains tax. The money remains in the account and continues to grow undisturbed. In addition, a tax-free withdrawal is possible later on if the “half-income” rule applies or if the child does not yet have any income of their own.
• Absolute flexibility: You can take breaks at any time or make larger one-time payments, for example, if you're planning to give a cash gift for Christmas.

How Grandparents Teach Financial Values

In addition to simply investing money for your grandchildren, financial education also plays a major role. People who learn early on how money works often make wiser decisions later in life. You can use investing as an opportunity to talk to your grandchild about finances. Explain how interest works, what a stock is, and why saving is important.

Many grandparents sit down with their grandchildren once a year, open the annual statement, and review the progress together. This turns an abstract financial product into a tangible topic. The grandchild learns that building wealth requires time, patience, and a good strategy. This knowledge is often just as valuable as the money itself.

Specific Reasons for Investing

There are many wonderful moments in life that are perfect for getting started or for expanding your investment portfolio.

A child’s birth is the ideal time to start building wealth for a grandchild. A baptism or the first day of school are also wonderful occasions to contribute to the savings plan instead of buying lots of toys. Christmas and birthdays are perfect for one-time contributions. If you, as a grandparent, choose a monthly contribution of 25 euros, you can add an extra 50 or 100 euros on these special occasions. The flexibility of the Invest4Kids concept makes this easy to do.

FAQ: Frequently Asked Questions from Grandparents

Financial matters involving grandchildren often raise many questions. Here is a brief summary of the most important answers:

As a grandmother, can I open a savings account for my grandchild?

Yes, this is possible at most banks, but it almost always requires the signature of the parent with legal custody. However, savings accounts offer extremely low interest rates.

Which is better: an account in my name or in the child's name?

An account in your name gives you more control, and you don't need your parents' consent. However, you won't be able to take advantage of the child's tax-free allowances, and the money will become part of your estate in the event of your death.

What role does gift tax play?

Grandparents have a very high tax-free allowance of 200,000 euros per grandchild every ten years. For most standard savings plans, gift tax is therefore not a factor in practice.

What happens when the stock market crashes?

The value of ETFs and global equity funds fluctuates. However, over the long term (more than 15 years), these fluctuations have consistently recovered in the past. Patience is the most important factor here.

Can I lower my monthly premium later?

Yes, with flexible solutions like Invest4Kids, you can adjust your contribution at any time or pause it entirely if you're ever short on cash.
