EFG welcome. Do pop in anytime. It's a really good question because having the 'reminders' around actually is not pleasant at all. And you're asking about an issue we all have to deal with at some point.
I packed anything I didn't want. I didn't consider whether he wanted it or not.
I'm not saying this is the best way of dealing with it, but like you I didn't want his stuff being here as an excuse for him turning up unannounced (a real risk and would likely have got the police involved - and at the time I was dealing with the police on other issues, nice as they were, I was finding all the legal stuff overwhelming), and secondly, I was sick of it littering my home as it was all bagged up in the spare room so anyone who stayed had to sleep in effectively a dumpster. All other storage places were stacked to the rafters so the spare room, his stuff had to occupy.
The only reason I could do this legally is because his name is not on this home. I'm the sole tenant. So this might not work for you...
First I wrote, all nice and polite, and requested he make arrangements to recover them. I didn't give a deadline (big mistake!).
He sent a list of ridiculous actions for me to take.
I ignored them all. They were not necessary. So left it for a while.
Then, sadly, I had to take him to court so was advised to not deal with it by my solicitor. The court outcome was incredibly unfavourable. For him. He got the hump. Big style.
It was very unfortunate that after the hearing, the solicitor advised that I get rid of his stuff now because he was going to escalate (!).
And we couldn't be sure how badly, so I needed to take the initiative.
For completely non divorce issues, I was also having to deal with the police as I'd been a victim of an incidental crime and the pre-trial hearings were gearing up for that. So I got their advice incidentally...and that's how I learnt about women's aid (another story).
So I wrote (with solicitor's input) and gave him two weeks' notice to make arrangements to recover. I also (critically) asked him to list anything that he thought he might want above and beyond his clothes/gear. He listed a few high value items**, and I packed them without argument.
Unfortunately, the solicitor also sent him the bill for her services (court ordered for him to pay) on the same day. This genuinely was unfortunate and not something planned. Can't speak for solicitor - I merely paid her to speak for me!
I believe I got seven nasty emails about that. With even more stupid instructions. It was upsetting at the time - but something I actually do laugh about now. And I really regret not doing some of the things he told me not to do (like piss all over his clothes!)...but I was trying to be dignified at the time. And to be fair, his sister was going to be receiving them, and she's lovely and didn't need to be handling my piss!
So I sent him two quotes for 'man with van' and said 'pay one of them or I'll dump in a charity shop'.
He paid. I got several more nasty emails.
He got his belongings back all in one piece. Piss free.
I got several more nasty emails. And accused of theft. And wanton destruction. And other acts of spite.
At the time, I was trying to be reasonable. It was really bloody hard work, I can tell you.
So what should have been something really straightforward was a horrendous ordeal.
So the moral of my story is, no matter how 'decent' and 'reasonable' you try to be - if Melodramatic Man wants to make a song and dance about it, then you can be sure he will. Otherwise, he'll just collect his stuff on request.
**In the middle of the final hearing he started making allegations that I had denied him access to chattels - I already had it in writing what he'd asked for. The judge was happy that chattels had been dealt with appropriately. I kept all the chattels that he left behind. They were worth a lot more than I 'gave away'. I believe I have some nasty emails about that.
It sucks when you've got a clever lawyer who knows the system.
So, my advice is
a) politely request at first.
b) follow up with a reminder and a deadline. Make sure you ask if there's anything else he'd like.
c) then send a firm reminder and give a final deadline.
d) ignore all the shite.
e) hire a man with van/dump in charity shop. After all, that's his choice.
f) show judge (if necessary) how you dealt with it reasonably.
g) go home to your litter free house.
