Exchange rates in financial settlement

We are trying to settle out of court. We own a propety and some savings in both France (where I am) and the UK (where he is). He is saying that any monies from France can't just be split and his share of euros sent to him, but rather that I need to take the exchange rate at the time into account and convert what I share with him to reflect this, so he doesn't lose out by the euro being weaker than the £. Is this correct? Would the courts do it like this?

What difference will exchange rates make?
If you split the value of something, say 50/50, then you get half each. What you then do with your half is up to you.
If you sold for €100 then you’d get €50 each. If you sold for £80 you’d get £40 each. It doesn’t matter what currency you express the value in.

If you have bank accounts in euros and it is savings in euros that are being divided it is fine to make part of any payment in that currency.
If you are balancing assets in euros against assets in sterling the exchange rate may be relevant. You would need to agree a date to crystallise the exchange rate to get a sterling equivalent. You could agree to change it if there are massive fluctuations but minor changes should not be an issue.

I think his concern is that, say there is €1 000 that needs to be split. I live in France, so get to keep €500, whereas when I send him €500 in the UK it will, for example exchange as, say, £427 at today's rate. So he considers that unfair! We came to live in France together. It has been his choice to go back to the UK, and I do not feel personally responsible for exchange rate variations.

Thanks for your answer. We have a house to sell in France and a flat to sell in UK. I guess some adjustments on the hard assets may be required. On the other hand, I believe a court would consider my housing needs, going forwards, and less that 50% is going to make finding even a humble home a challenge for me here.

It is also possible to transfer to a card that accepts different currencies like Revolut.

He can keep it in Euros and exchange it at any point to whatever currency he sees fit when the exchange rate changes in his favour.
