The court may consider many factors when determining an allocation of spousal support. These are sent out specifically in T.C.A 36-5-121(i) which states:
In determining whether the granting of an order for payment of support and maintenance to a party is appropriate, and in determining the nature, amount, length of term, and manner of payment, the court shall consider all relevant factors, including:
(1) The relative earning capacity, obligations, needs, and financial resources of each party, including income from pension, profit sharing or retirement plans and all other sources;
(2) The relative education and training of each party, the ability and opportunity of each party to secure such education and training, and the necessity of a party to secure further education and training to improve such party's earnings capacity to a reasonable level;
(3) The duration of the marriage;
(4) The age and mental condition of each party;
(5) The physical condition of each party, including, but not limited to, physical disability or incapacity due to a chronic debilitating disease;
(6) The extent to which it would be undesirable for a party to seek employment outside the home, because such party will be custodian of a minor child of the marriage;
(7) The separate assets of each party, both real and personal, tangible and intangible;
(8) The provisions made with regard to the marital property, as defined in T.C.A.§36-6-121;
(9) The standard of living of the parties established during the marriage;
(10) The extent to which each party has made such tangible and intangible contributions to the marriage as monetary and homemaker contributions, and tangible and intangible contributions by a party to the education, training or increased earning power of the other party;
(11) The relative fault of the parties, in cases where the court, in its discretion, deems it appropriate to do so; and
(12) Such other factors, including the tax consequences to each party, as are necessary to consider the equities between the parties.
