How do I transfer the house deed from my dad to 4 of his chlidren and a son in law whom is a veteren in El Paso Texas?

If your father is living, he will have to sign the deed.  He may wish to reserve a life estate in the property so he can use it while he is living.   If your father is deceased it will be necessary to have a probate proceeding to transfer title.  the issue of who will take title will be determined by his will, if he has one; or, by the laws of descent and distribution of the state of Texas (I assume the property is located in Texas).   I hope this helps.   Russel L.
