An owner sold a parcel of real estate to a buyer with the stipulation that the buyer was not allowed to sell alcohol from the prem- ises. The buyer sold the property 10 years later to a buyer who converted the build- ing into a convenience store that sold beer. Should the owner or owner’s heirs claim a right of re-entry, what would be the basis for the lawsuit?

A covenant is a contractual promise that runs with the land and is enforceable through an injunction or damages, not through forfeiture of title — the question specifies that the owner seeks a 'right of re-entry,' which is a remedy for a condition subsequent, not a covenant violation, making this classification legally incorrect.

A condition precedent is a condition that must be satisfied BEFORE a property right vests or a contract becomes effective — it precedes the transfer, not follows it; since the property was already conveyed and the restriction applied to future use after the sale, this is a post-conveyance condition, not a pre-conveyance one.

The Statute of Frauds requires certain contracts, including real estate contracts, to be in writing to be enforceable — it governs the form of the agreement, not the nature of a property condition or the grantor's right to reclaim property upon a use violation, making it entirely inapplicable to the legal basis for a right of re-entry lawsuit.
