Projects that help people navigate the civil court process, including for small claims cases, are also in line to benefit. Organisations such as Citizens Advice and housing and homelessness charity Shelter Scotland are among recipients.
Slab chief executive Lindsay Montgomery said the money will "enhance the provision of help for people in Scotland who require assistance with legal and financial problems".
He said: "We appreciate the financial support from both the Scottish Government and the Money Advice Service for this significant programme of grants.
"The projects will play an important role in helping find long-term solutions for people struggling with financial difficulties by dealing with the underlying debts that are often the root cause of housing problems. Spread across Scotland, they will be seeking solutions that prevent homelessness and try to put in place sustainable debt solutions."
Justice Secretary Kenny MacAskill said that the funding underlines the Scottish Government's commitment to "ensure that people get the help they need to deal with problems such as multiple debts, repossession and eviction".
