Establish a workable, permanent space to serve as a place for handling information and storing most records. Make it pleasant, well arranged with good lighting to encourage you and others to use it. A computer at home will help with record keeping but it's by no means a requirement. Choose one person to be responsible for getting the routine financial tasks done but all should share duties. Sharing family income means knowing income and outgo, which, in turn, requires information and records.
Sound decisions depend on the process.
If you are a single parent, get older children involved in record keeping. Create a record storage system based on value and use. A bank's safe deposit system is probably the best place for valuables and documents difficult to replace. These institutions provide maximum protection from theft, fire, and other natural disasters. Records often kept in a safe deposit box are titles, certificates, including bank, birth, marriage and stock, the original of Last Will and Testament, and pictures or videos of valuable or collectibles for insurance purposes.
