Hi, If your wife is refuse to accept the Summons from the Court then you have to take the steps through the Substitute service like affixture of the Summons in the conscious part of the House or through paper publication in leading news paper.
2. Don't file any case against your wife and filling injunction suit will not help you and you just running from pillar to post and post to pillar.
3. Suppose, If she lodge a police complaint against you and your mother then the police will not arrest you immediately, first they have to verify the genuineness of the Complaint and then they have to issue notice to you and your mother and thereafter they have to refer the matter to the mediation to settle the matter amicably so there are so many process as per law and in the mean time you can also apply for anticipatory bail in the Court.
