Sorry Lad, but alimony is not determinate on fidelity. Unfortunately, it becomes a matter of whom is the main provider. Now that doesn't necessarily mean that person will pay alimony, it just means that if said person was the main provider and support of spouse they may have to pay. Each state is different with regards to economic situation.
P.S. did you have a pre-nump. that specified fidelity?
Speak to your attorney! Be sure he or she is a good one! And most of all don't let your lawyer ramrod you! Be aware of every word spoken and every paper signed by you. If you don't understand something have them explain it until you do. You pay a lot of money for their time so take advantage of it. And last but not least, big question, do you have children? This can also determine some type of alimony either to yourself or your spouse. Good luck!
certainly you can. you need to contact a family law solicitor and also social services. an inspection will be done to see if you a suitable carer. also, you need to prove your mothers addiction, possibly a photo or a needle or something. your solicitor will use this as evidence, as your brother is young he may not be used as a witness to your mothers acts and because he may love and see no wrong doing in her acts he will possibly defend making your case difficult. what you must not do is try and persuade him that his mother is a bad person, because if a custody case went to court he may say that you told him to say........making you look as bad as your mother. you also have to prove that you can be financially stable to care for him and also be able to apply effort to his school work and his own effort. make sure that both you and your husband are ready also because situations like these cause an awful lot of trouble, beleive me. I know exactly what it like, ive experienced a similar situation without drugs. i hope i was helpful to you!!
