Life Interest In A Property

[AliceSmith1979]

If a property has been devised and bequeathed to me and my siblings, and life interest has been given to my mother and her sister (to be equally shared as a weekend retreat) can my Aunty or Mum sell the property without me or my siblings permission?? If we were all to agree to sell, how would you think the monies would be divided amongst the 5 parties involved?

The short answer to this question is "no".
You can all (not majority, all) agree to sell the land - but it's not their's to sell of their own motion.

If we were all to agree to sell, how would you think the monies would be divided amongst the 5 parties involved?

That is entirely a matter for negotiation between yourselves - there is no single "right" way to distribute those proceeds.
Bear in mind that the financial and tax implications may vary from sibling to sibling.
