Tennessee Code Title 30. Administration of Estates § 30-3-103

(b)(1) When any such policy, charter or bylaws executed or adopted after February 15, 1941, contains a provision requiring a beneficiary to bring suit upon a claim of death within one (1) year or other period after the death of the insured, and the fact of the absence of the insured is relied upon by the beneficiary as evidence of the death, the action may be begun, notwithstanding such provision in the policy or charter or bylaws, at any time within the statutory period of limitation for actions on contracts in writing dating from the date of the giving of written notice of such absence to the insurer, which notice shall be given within one (1) year from the date when the beneficiary last heard of the absent insured. If such notice is not given, then the statutory period runs from the time when the absent person was last heard of by the beneficiary.

(2) Provided, that if the seven (7) year absence is relied upon to establish death, then the statutory period of limitations shall only commence to run at the end of the seven (7) years.
