Our relationship is 5 years back can I marriage to her

Ans: Dear Gopi,
I don't think you and this lady have spoken about the structure of the live-in.
Live-in seems like a very fancy thing to do, but it lacks a structure that marriage provides. So, if you are one of those people who needs the security and stability that marriage can offer and live-in can't, then maybe you are in the wrong place. Live-in isn't going to give you any commitments unless you both have agreed to live-in and see if it can turn into a commitment. If both of you have agreed that it is going to be a live-in only, do factor in how you are going to raise your respective children and also explain this facet of live-in with them.
Marriage definitely will give the children the necessary stability but if both the partners are mature enough to take on a live-in, the love and support in that environment can also welcome the children warmly.
So, it's time to evaluate what you seek: a live-in or a marriage and she must answer the same. Sit down together and discuss this at length begore taking any big decisions.

All the best!

Ans: Dear Vinay,
If neither of you are currently married to anyone else, then there shouldn't be any legal issues. But if you or your partner is still legally married, or haven't opted for divorce yet, or are in the process of divorcing, then it isn't possible to get married right now. Please seek the help of a legal expert to get better clarity on the matter.

Best Wishes.
