My father died without a will — who inherits his house in Texas?

When a Texas resident dies without a will (intestate), the Texas Estates Code §201.001 governs who inherits. With no surviving spouse and three adult children, his estate will pass in equal shares — one-third each — to all three children. The house will need to go through the probate process. You can file for a Muniment of Title (a simplified process if there are no debts other than the mortgage) or a full independent administration. You'll need to file in the county where your father resided. Consult a probate attorney to choose the most efficient path.
