Laird (//) is a generic name for the owner of a large, long-established Scottish estate. In the traditional Scottish order of precedence, a laird ranked below a baron and above a gentleman. This rank was held only by those lairds holding official recognition in a territorial designation by the Lord Lyon King of Arms. They are usually styled [name] [surname] of [lairdship]. However, since "laird" is a courtesy title, it has no formal status in law.
The Lord Lyon, Scotland's authority on titles, has produced the following guidance regarding the current use of the term "laird" as a courtesy title:
The term ‘laird’ has generally been applied to the owner of an estate, sometimes by the owner himself or, more commonly, by those living and working on the estate. It is a description rather than a title, and is not appropriate for the owner of a normal residential property, far less the owner of a small souvenir plot of land. The term ‘laird’ is not synonymous with that of ‘lord’ or ‘lady’. Ownership of a souvenir plot of land is not sufficient to bring a person otherwise ineligible within the jurisdiction of the Lord Lyon for the purpose of seeking a grant of arms.
Historically, the term bonnet laird was applied to rural, petty landowners, as they wore a bonnet like the non-landowning classes. Bonnet lairds filled a position in society below lairds and above husbandmen (farmers), similar to the yeomen of England.
