My daughter-in-law left home about a month back saying not to return. On other occassions also she has done this and has returned. This time it seems she may stay longer with her parents and has also plans for mutual consent divorce - we heard them saying. She has gone on her own in spite of our requesting her to stay with her husband. She has 20 months old baby. My son got married 3 years ago. What legal steps you would suggest under the present circumstance.
