Legal Question in Family Law in Texas

Re: common law

You would likely have to assert your interest in the property at the time of his death. Depends on your relationship with his children which sometimes changes when estate money arises. Whether or not you are common law married depends on the circumstances. Certainly buying a house together might be considered some evidence of a common law marriage, but there are other factors as well. If you and he do not want to get ceremonially married, you can register your relationship at the courthouse. See a lawyer. Shouldn't be that expensive. Good Luck.

Re: common law

It generally takes more than just buying a house together to be common law married unless the deed states you are purchasing the house as husband and wife.

If both your names are on the deed then his heirs will have a claim to his ownership interest in the house upon his death unless he leaves his share to you in his Will.
