my fiancee is paying alimony to his xwife - will she will entitiled to an increase when we get married if I work?

Normally alimony is limited to the ex's ability to pay. In certain situations the payor may be asked to pay more if the new marriage means he has less expenses. For example. if his rent is $1,000 a month and now he gets married and the new wife pays 1/2 of the rent then his rent is now $500 per month. Sometimes the ex succeeds in getting alimony increased if she can show 1) her need 2) her ex's ability to pay. This is very fact specific. An ex cannot go to family court and demand more money for the sole reason that the ex has married.
