The general rule in court proceedings is that the losing party must pay the successful party's costs: not their actual legal costs, but a contribution to those costs based on a tariff of charges.
In a recent case out of the BC Court of Appeal, Rosas v Toca 2018 BCCA 191, the court altered the law surrounding contractual modifications to an existing agreement. Until now, in order for a modification to an existing contract to be legally binding, it has been required that there be some new consideration flowing between the parties. Consideration has been required in order to draw the line between gratuitous or morally based promises and those that were legally enforceable.
When a debtor becomes bankrupt, there may be suspicion as to whether the bankrupt has made full disclosure of all assets or dealings with the bankrupt's assets prior to the bankruptcy. The bankrupt's conduct prior to discharge may also be in issue. The trustee in bankruptcy has the obligation to make inquiries, but if the bankrupt is uncooperative, or if information is required from someone other than the bankrupt, more aggressive steps may be required.
