Is there a difference in how temporary spousal support is figured versus final spousal support"
From what I have read it appears that there is a difference here in how things are determined, although there is most likely an overlap of some factors. Here is what I have found: "In Texas, temporary spousal support is deemed appropriate if a spouse is unable to support him or herself and the spouse is used to a particular living standard during the marriage. If a spouse demonstrates financial need at a temporary hearing — based on monthly costs for the house, car, children, utilities, groceries and other living expenses — the court will probably award temporary support or alimony while the divorce is pending. After a divorce, the court may award alimony to a spouse after considering a number of factors, including the length of the marriage and the income, education, training and health of both husband and wife. Spousal maintenance after the divorce may be in the form of a lump sum payment, the gifting of a house, or permanent spousal support." Good luck.
