English: bar separation
Welsh: ymwahaniad bar
Subject: Cyfraith
English definition: Charities cannot run a bar or trading activity on a regular basis without committing a breach of trust and incurring a tax liability. You must separate your bar and trading from the charitable activities of your organisation. Simply keeping a separate set of accounts or having a bar sub-committee is not enough.
