FWIW, if your relative is from out of state, I wouldn't trust ANYONE'S advise on hunting requirements. I would click the link provided by one poster and read and understand everything first hand from TPWD.
Why? Because once you cross state lines with game killed in ANY state, you then come under Lacy Act jurisdiction. Want a good scare? Google Lacy Act violations and see what can happen if you don't fill out a tag correctly, or sign the wrong part... or ANY minute violation.
For the tiniest infraction the feds can use the Lacy Act to fine you, the rancher, the outfitter, and guide (virtually everyone involved in the hunt) up to $500,000.00 and imprison you for 10 years.
I don't take peoples' word for stuff that serious.
