In practice, disagreements resolve fastest when both owners are negotiating from one independent valuation rather than each owner's own estimate, since a number one side produces is rarely one the other side accepts at face value.
Where the owners cannot agree at all, whether they are former spouses, siblings who inherited the property together or business partners, the unresolved dispute can end up in front of the Court of King's Bench, a process that typically adds a matter of weeks before most owners settle.
