Rights During Separation
Yes.
Yes.
It depends on a lot of factors such as the amount of time your husband now has with his daughter, the reasons why his daughter wants to live with you 1/2 the time. Are there abuse or neglect issues going on at the mother’s house? Is she having social adjustment issues, problems with school or mental health issues? These are all questions which must be answered to determine your chances of success. If you don’t have enough to warrant a 50/50 time split with his daughter, you may be able to increase the amount of time you now have regardless.
Good question. The answer is YES. If you and your new wife file joint returns, the IRS can and will seize the entire amount if it owed. The only way to protect yourself is to file separate tax returns or adjust your withholdings during the year so that you will not be entitled to a tax refund. Therefore, the IRS will not have anything to seize.
You definitely have rights. Do NOT sign anything. You will need to go to court to get an allocation of parental responsibility which will determine decision making and parenting time as well as child support.
It depends on the court orders that have been entered. Is there an order that she pay you child support? Was this a divorce, allocation or paternity action? If she is that unstable, why would you even consider giving her custody of your step daughter? If the therapist is concerned that she has sociopathic tendencies, you should consider filing a motion to restrict her parenting time, request supervised visits or therapy if appropriate.
