¶1This matter came on for a hearing on March 5,1999, on Phyllis Hering’s demurrer to F. Shriver Hering’s petition to terminate spousal support. The Court after hearing argument of counsel took the case under advisement. Having now had an opportunity to consider the arguments of counsel and to review the memoranda submitted, the demurrer is sustained for the reasons stated below.
¶2On February 28, 1995, the Herings entered into a marital settlement agreement which, among its provisions, provided for spousal support to Phyllis Hering until Mrs. Hering remarried or either of the parties died. The Agreement was incorporated into a final decree of divorce entered on March 3, 1995.
¶3On January 20, 1999, F. Shriver Hering filed a petition seeking the termination of payment of spousal support based upon the 1997 amendments to Title 20 providing that a court could terminate spousal support upon clear and convincing evidence that the spouse receiving support was habitually cohabiting with another person in a “relationship analogous to marriage.” Va. Code Ann. § 20-109(A). Mrs. Hering demurs to the petition saying that as the parties’ Agreement provided only that spousal support would be terminated on *441the remarriage of Mrs. Hering or the death of either party, the 1997 amendments to § 20-109 unconstitutionally impaired the obligation of their Agreement.
¶4In response, Petitioner relies on the line of Virginia cases that draw a distinction between contractual provisions for spousal support incorporated into final decrees and those that are merely approved in final decrees.
¶5*442Petitioner here argues that Shoosmith II holds that alimony, even if the subject of contract, is always subject to being changed by the legislature. This is not the holding of Shoosmith II. That case merely held that the Shoosmith contract provisions were incorrectly described as alimony in Shoosmith I. The only implication in Shoosmith II applicable to this case is that a contract incorporated into a final decree is alimony and thus subject to the statutory provisions related to that subject at the time the contract is effective. See Durrett v. Durrett, 204 Va. 59 (1963) (where contract provided for alimony to wife for so long as she lives but was silent as to payments after death of husband, alimony ceased upon his death because under Virginia law, alimony does not continue after death of payor spouse).
¶6Applying the 1997 amendments to § 20-109 to the Agreement would be an unconstitutional impairment of contract, and therefore, the demurrer to the petition is sustained. Petitioner is granted permission to amend his petition to allege that the spousal support provisions should be changed due to a change in circumstances as this is expressly permitted by the marital settlement agreement and is not contrary to Hollowell v. Hollowell, 6 Va. App. 417 (1988). That case holds only that cohabitation alone is not a change of circumstance warranting recalculation of spousal support. Here, Petitioner wishes to allege that as a result of her cohabitation, Hering’s financial needs have changed. Hollowelldoes not preclude such a petition.
¶7Petitioner also cites Richardson v. Richardson 47 Va. Cir. 412 (Accomack 1998), and Biddle v. Biddle, 46 Va. Cir. 433 (Stafford 1998). These cases both apply die 1997 amendments to pre-1997 property settlement agreements. In neither case was an impairment of contract argument either raised or discussed, and therefore, they do not provide any guidance on that issue.
