partage amiable

Oh, yes. That's a particularly good option for this case, I think. Sorry, I didn't see that one in your post.

@AllegroTrans -- Yes, it wouldn't make sense to give the tires to one family member, the crank shaft to another, etc. ;-)

Yes, this is just about who is to get the car, XXX YYY and ZZZ are the joint statutory heirs to the moveable assets and they have decided to give the car to Mrs DDD who is the heir to the house (rather than cut it up into three parts!)

If this is just about who is to get the car, rather than about the general partition of the estate, then my option of "agreement (by heirs) can be used. Something like: the heirs agree (come to an agreement) that the vehicle [...] will be allocated (in sole ownership) to Ms DDD OR the heirs agree that Ms DDD will take sole ownership of the vehicle.

Borrowing from both Yvonne's and Karine's suggestions, perhaps a wordier and less literal option could be: amicable resolution to divide property.

Translation example:
"...have decided, subsequent to an amicable resolution to divide property..."

Or even "upon mutual agreement to divide property," from what I infer from Karine's suggestion.

Another option could be to replace divide with distribute, which is the term I see in some legal sources.

There is no particular rule that says you must use an exact two-word term to replace the one in the source text. I suppose it comes down to personal preference to some degree.

I'd personally opt for a solution that would be easiest and quickest understood by the target audience, which in many cases may require some level of elaboration or a more descriptive approach.
