Delila
I have no idea how many different kinds of business partnership there are GSM, that’s why I’m asking you what sort this is.
It seems a reasonable question as you say that the OP is legally in partnership with her husband, and this should affect her decision regarding spending a day a week with her new grandchild.
I'm genuinely curious about that aspect too. As I've said earlier in the thread, my husband runs his own business and I 'help out', both on a practical level at times but also doing all the administrative side of things. I've never entered into any kind of legal contract, my name isn't on any paperwork - am I 'legally in partnership'? I don't think so. To all intents and purposes, it is his business. Perhaps that's the nature of the arrangement the OP has with her husband too.
