Apologies, don't quite know what the correct description is.
Me and next door are replacing the (invasive) ivy hedge in the garden with a fence, and going 50/50 on the cost. Neither of us can 100% remember who's boundary it is, I vaguely remember it being mine, but might have imagined it. We're not sure and very easy going, so just splitting it 50/50. (I'm happy for them to have the posh side on their side because I want the support slats on my side for fixing things to easier.)
The Neighbour joked last week I needed to remember to ask for an invoice so he could claim it on expenses by pretending it was for one of his rental properties. I just laughed it off, but he's just rang me from work to give me the address I should ask the gardener to put down on the invoice.
I don't know if I'm being too sensible and boring, but this just doesn't sit well with me. His girlfriend has already given me their half of the money in cash, and she wasn't bothered enough to mention it. I know I'm not going to get any police knocking on my door obviously, but it really goes against my morals. The Neighbour is well known for his sense of entitlement and back handers (eg, me and the other side paid to have dropped kerbs put in by the council, but he just bribed the workmen and got his front done for free). I work for the NHS and we're on our arse and it's people taking every opportunity to not pay tax that contributes. It's a real bugbear of mine.
Am I being unreasonable by refusing to ask the gardener for a fake invoice?
Or opinions on how I can explain this to my slightly intimidating neighbour? I don't feel confident because this might totally be me being an absolute wet-wipe and everyone else on the planet happily fleeces the tax man given the opportunity, and I shouldn't stand in his way. Ultimately good neighbour relations come first. I just don't know.
Thoughts?
