You may have a spousal support obligation, but it is impossible to determine whether this is the case or how much you might owe without additional information.
Further complicating any spousal support obligation arising in a same-sex marriage is the fact that your support paid will not be tax-deductible to you or taxable to her at the federal level. Accordingly, you would want to deviate from any temporary support calculations.
You should consult with an experienced family law attorney in your community to do a more thorough analysis of whether or not you would have an obligation and how much that obligation might be.

I agree with Mr. Rudy that it is difficult to know if and how much support you might be asked to pay. Assuming that some support would be ordered, there is a rule of thumb that, in regards to a short marriage (less than 10 years) the support obligation would last one have the length or your marriage, or in your case, about 2 years, three months.
If you earn more than your spouse you have some support liability here, even a "short term" domestic partnership. Rule of thumb is 1/2 the length of the marriage. Its possible to impute earnings to her based on ability to work also there should be a Gavron warning given when and if a spousal support order is made , advising her that the policy of the state of California is for the supported spouse to become independent and self supporting one day.

I agree with the other attorneys that you may have a potential spousal support liability for a limited period. However, to get meaningful advice as to amount and duration of support, you should consult with an attorney.
