в данном контексте: deed = title deed = deed of transfer = документ о передаче права собственности (на объект недвижимости),

о том, что "title deed" - это не Real Estate Contract или Sale Contract (наш аналог - договор купли-продажи), можно прочитать в этой ветке с пруфлинками, если читать не по диагонали.

а также "title" или "title deed" называют красивое свидетельство, выдаваемое БТИ (у нас) и подтверждающее наличие такой записи в их реестре на данный момент (наш аналог - "свидетельство о государственной регистрации права").

Если у предполагаемого собственника "wild deed" (предшествующий собственник не был зарегистрирован в реестре должным образом),
то его право собственности туманно - "clouded title" / "cloud on a title".

// A clouded title/wild deed will diminish the market value of the property.

// This property is not saleable, due to a clouded title, the ... assessor's office considered the land grant deed a “wild deed” that was ...

// Currently title companies are being hit with large claims due to the loss of priority of liens and loans (another form of junior and senior rights). A bank cannot prove that it actually owns the foreclosed property because the note and the mortgage are separated creating a “wild deed.” As a result, a first subsequent buyer of the foreclosed property may not be able to obtain title insurance unless the bank agrees to indemnify this first subsequent buyer against any title claims or losses as part of the first subsequent buyer’s title insurance policy. Even if the bank and the title insurer work together to provide title insurance to this first subsequent buyer for the foreclosed property, when this first subsequent buyer goes to re-sell the foreclosed property to a second subsequent buyer, the first subsequent buyer will have a clouded title and “wild deed” and the second subsequent buyer will not be able to obtain title insurance and financing without indemnity from the first subsequent buyer (which in all likelihood this buyer cannot provide).
