I am confused of uses of belong in sentences. I know belong is intransitive verb so it should not be used in passive sentence.
But still I can see it is used with "is" and "was" like below examples a) Can we use "Belong" to tell status of something like below examples?
Examples
a) This property is/was belongs/belong to us
b) This property belongs/belong to us
c) This property has/had belonged to us
Please help me to understand correct use of belong in English sentences
