A company has 2 directors with 50/50 shareholding. However, one director has moved on and has resigned. This director has a negative DLA account. As the directors are father and son, the father is happy to write this debt off, as the son could never repay it. Can this be done as an exchange for the shareholding, or is the shareholding irrelevant. There is question that the son may come back claiming half of the company's assets.
