1. Record the whole negotiation process between you and the mistress, if she threatens and intimidates you into divorcing, this is all evidence.
2. Let her do a paternity test and tell her that you will definitely raise it if it is your husband, and you will definitely get custody of the child. You will raise the child with your husband and make her understand that it is not good for her to have this child, and she will not be able to use the child to get money.
3. Tell her that if the child is not your husband's, let her be self-respecting. And tell her that you and your husband will never divorce.
4. Don't trust your husband anymore, there are only 0 and countless times of cheating. Be careful that he and the mistress join forces to transfer the joint property of the husband and wife! It is necessary to take advantage of the remorse attitude of men at this time to protect their legitimate rights and interests!
5. Let the man make a will, and the contents of the will are designated to be left to the children of your husband and wife, not to the children outside. However, a will can be amended over and over again, and can only be valid with the last will before death.
6. Sign a marital property agreement, which stipulates the division of the joint property of the husband and wife, and the maintenance of the third child in the future will only be part of the man's personal property to avoid damaging your property interests. Make sure you have a legitimate interest in getting a divorce later.
