Are there any pitfalls to look out for in doing this? Also, is it always the norm that owners ask for small financial contribution? I know its usually the reason they part loan their horse. I'd like to share a horse with someone who simply doesn't have the time to exercise properly, so I'd therefore just donate the time in exercising/evening feeding etc but at the moment I couldn't really donate much in money. Obviously it'll have to be a weight carrier, at least 15hh or a very chunky 14.2hh + pony, and nice temperament so I'll be ok riding on my own in a menage. I'm just trying to find ways of doing more riding for less money basicially, but I'll be prepared to put in more time and work like mucking out/feeding/grooming.
