Wedding Cost

I am getting married in 5 months. My mum is giving us a budget and we dont know how to ask if his parents intend on contributing to the cost of the wedding. Please help, how do I bring this subject up? What do I say?
P.S I have a fantastic relationship with his parents and have known them for over 5 years. I dont expect them to contribute a lot, more looking to ask if they plan on contributing at all. We are able to do the wedding on the budget mum has given us, but would like to know what their plans are.

Well, in most cultures the bride’s parents tend to pay for the wedding ….but in this day and age, everything is 50/50. So perhaps…depending on your budget u can bring it up to ur fiance and say….my parents are contributing this much…how much are your parents willing to contribute. Note, it also depends on how much the wedding is too, plus how much you and ur fiance intend to put into the wedding as well. Another thing to do is say this is the budget, this is how much we have, and this is how much we need, ( do it during a family dinner or something) and then ask if people can pitch in to help cover some of that…and perhaps they will help.
