Unfortunately, failing to plan your estate can lead to many consequences for those you love. Suppose you become incapacitated. In that case, only someone appointed by a court can sign for you.
The court will also oversee and control what happens to your assets with a conservatorship or guardianship (the terms used vary by state). This situation frequently becomes time-consuming and expensive. It also goes on public record and may even be challenging to end if you recover from your condition.
If you pass away without a legally binding estate plan, a court-supervised probate proceeding will distribute any assets owned solely in your name per your state's intestacy laws.
Many states provide that your spouse and children each receive a share, even if your children are from a prior marriage or are adults. In this situation, your spouse might only get a small portion of your estate, which might not support them.
If your children are still minors, the court controls their inheritance. If both parents die, the court will appoint a guardian since it's unknown who you wanted as their guardian.
