Nikaah & Marriage Issues

Taking a second wife

Q: I have been married for eight years. My wife is not interested in sex. We can go 5 to 6 months without being intimate. She never adorns herself or makes herself look attractive. It has become very difficult for me. I really don't want to split my family up by getting divorced. My question, am I in the right by getting a second Wife?

Time of walimah

Q: Please advise how exactly is a nikah consummated. Is it necessary for the couple to perform intercourse or even if they slept together that shall be sufficient to perform walimah.

Court marriage

Q: My question is regarding my marriage. When I met my husband I wasnt paying much attention to religion so we married in court as civil marriage. My father and mother left me alone in another country so I didn't have any wali present on the day we got married. Now since I learned more about Islam and I am concerned, I would like to know if our marriage is valid?
