The partner threatened to renege on the contract.

Dead on, in the US anyway.

rooted in "renegotiate"

U.S.

the contract partner threatened to rescind the contract

So if my actual sentence says "Nur bei Androhung einer Vertragsrückabwicklung wird...", could I say:

Only if a recission of contract is threatened will...

Renege has a negative implication of not keeping ones end of the deal.

Rescind is more likely a withdrawal from the contractual obligation.

Hi Helmi!!!

Good point.

US

Must be an English (UK) expression.

Never heard recission before....

Damn Southerners!! :-)

Sorry: Typo!

I meant: rescission!!!

Does that work? :o)

@ J, how about: Only in the event of threatening to rescind the contract will this or that happen.

This works, thank you all!!!

Is a word that means the same as Rescinded in the US Thesaurus...

only with the threat of contract rescission will

I'm with Helmi on this one..... but if you like that word it is not incorrect!
