Marrying a malaysia girl this april. Advise for solemnisation to be held in Singapore or Malaysia ? Its a muslim marriage btw.

We were together for 8 years and now we have decided to settle down. Initially, we have decided to

have our solemnisation to be held in Singapore. However, her dad ( already divorse with her mom ) would want us to perform the solemnisation in malaysia instead as he mentioned its much better for her daughter and grandchildren's future. We chose Singapore in the first place as it was her mom told us that she has a friend who is married to a singaporean too and advise as it would be better in terms of processing of documentation in the event of death or divorse. Now, her dad wants me to provide the facts and proof that performing the solemnisation in Singapore is a way to go instead of Malaysia. Apart from that, her dad also mentioned for her daughter to give birth in Malaysia. I would appreciate if any of you could give me any advise as i am having a hard time with this. Thank you.
