Legal assistance with chasing a debt in Singapore

We require legal assistance for chasing a debt in Singapore. The debt relates to a sub-tenant who occupied space in our office. There is a signed agreement and a history of payments before the tenant stopped paying and dissappeared. The tenant ultimately went delinquent. We have the Acra business profile of the company which includes 2 directors. The amount is small however the principle is our driver. Our goals are to: - Lodge a claim against the company to register the debt. - Understand what the legal position is with regards to the property they left behind in the space. Can we just throw it out. - Wrap up the matter so we can move on without any recourse from the sub-tenant. We are looking for someone who understands debt recovery and landlord/tenant contracts in Singapore who can advise on best course of action, write the necessary letters and assist us to conclude this matter the right way. We look forward to hearing from you soon.
