A legal description is eligible for recordation if the document contains a reference to a legal survey or is capable of being indexed in one of the two statutory numerical indexes maintained by the office of the Register of Deeds for that particular county.
If a legal description includes a reference to a platted division or subdivision, the legal description should also identify the lot or tract number, the block or tract number and the name of the platted addition or subdivision taken directly from the recorded plat. The legal description should also include a concluding reference identifying the county and state where the plat is recorded along with the book and page.
