Sales contract .... correct verbage, reference 1031

[Mike Costello]

New to BP ... so, thank you in advance for your responses.

I have owned a SFH 1031 exchange property for exactly 5 years, two of which i used as my "Primary" residence. I am now selling and want to take advantage of 1031 / 121. What reference to 1031 if any, does my lawyer need to include in the sales contract to make sure I comply with the rules. I am located in CT.
