Journal entry for payment of unrecorded liabilities in cash is given as-
Cash/Bank A/c Dr.
To Realisation A/c
The same entry is given for the recording of the sale of unrecorded assets. Why is it so?
For payment of any Unrecorded Liability:
Realisation A/c ...Dr.
. . To Cash/Bank A/c
For realisation of any Unrecorded Asset:
Cash/Bank A/c ...Dr.
. . To Realisation A/c
[Please note that the entry given by you is for realisation of unrecorded assets, not for payment of unrecorded liabilities. For each of these purposes, we pass different journal entries.]
