It is essential to review your estate situation regularly in order to adapt to changes. These may include sales, purchases, investments, assets acquired abroad, or changes to tax and civil law. Personal and family events can be just as important triggers for reassessment.
Let’s consider the following example. You marry in Belgium without a marriage contract and are subject to the Belgian legal regime. With your notary, you draft a will and plan to protect the surviving spouse by bequeathing the available portion. However, your children live in the Grand Duchy of Luxembourg for professional reasons. If, upon retirement, you move to Luxembourg to be closer to your children, your matrimonial property regime—and therefore the effectiveness of your arrangements to protect your spouse—may be impacted. This is precisely why periodic reviews are essential.
