Definition - What does Voidable mean?
Voidable is a term that means that something is not fully void but that it may have properties that can cause it to become void.
In terms of contracts, the word "voidable" refers and is used to define a contract that remains valid until the parties involved declare it void.
Justipedia explains Voidable
There are various things that can make a contract voidable; these include fraud, undue influence and misrepresentation. For example, a minor (under the age of 18 years) entering into a contract with another party generally creates a voidable contract since minors are not legally eligible to enter into contracts except under rare circumstances. The minor may also decide to affirm or disaffirm the contract.
