3 day or 30 day notice to vacate with no written lease agreement?

[onthepipe]

What is the name of your state (only U.S. law)? TX
I am an executor of an estate for which there is rental property. The deceased owner let a tenant live rent free for 12 years in one of these properties on the verbal terms that the tenant would "fix up" the property. The tenant destroyed the property and now refuses to leave without legal action. Can I serve a 3 day notice to vacate or does law require a 30 day notice to vacate? There is no written lease agreement.

The shorter 3 day is more often used when there is a lease violation or non payment of rent , Ill bet it would be easier to go 30 days since you do not have a written lease and the person has never paid rent , this way at the end of the notice time if the person doesnt leave you can take them to court and let them explain to a judge what part of the notice they did not under stand. Not that it will do any good , In the very end if they still wont leave you may well have to have the sheriffs dept carry out the courts order and go and remove them from the property.
