Morena – check out the advice in the Retail and Legal forums on this site as there are some great Korero around this topic. Short answer, look at your lease terms, does that include a clause around rent abatement in the case of emergency? Next talk to them, if they want move, then think about what other options – the most extreme is you make an assessment of what you think is reasonable to pay, and just do that. Paying nothing is a risky strategy. Then reach out and explain why.
