IPA: /ɪnˈkʌmbərənsər/
KK: /ɪnˈkʌmbərənsər/
A person or entity that has a claim or burden on a property, often affecting its value or use.
The encumbrancer had a legal right to the property due to the mortgage.
Encumbrancer → It is formed from "encumber" (from Old French *encumber*, meaning to hinder or burden) and the suffix "-er" (meaning a person who). An encumbrancer is a person or entity that burdens or hinders another's property or rights.
Think of someone who 'burdens' ('encumber') another's property — the '-er' just means a person. An encumbrancer is someone who causes a burden.
