Need, no. Should yes. Now, if theyu2019ve been there 3 years and the place in good shape, Iu2019d probably be generous on some terms, but perfectly clear. But the lease makes things clear to BOTH parties about what is expected.You can find many templates on line. Iu2019d suggest looking at them and adopting one to your needs.Remember, itu2019s valid only if both sides sign it AND itu2019s not in violation of state or local laws. Also, most templates will include a clause that states something like, u201cif any part of this lease is found invalid, the rest will remain in effectu201d. Keep that, it can be important.Iu2019m not a lawyer, and this is not legal advice.
