Probate means that there is a court case that deals with:

Transferring the property of someone who has died to the heirs or beneficiaries;
• Deciding if a will is valid; and
• Taking care of the financial responsibilities of the person who died.

In a probate case, an executor (if there is a will) or an administrator (if there is no will) is appointed by the court as personal representative to collect a decedent’s assets, liquidate liabilities, pay necessary taxes, and distribute property to heirs, all under the supervision of the court.
