Once you've claimed, there are several options. If the defendant has not replied after 14 days you can apply for a judgment by default. If no payment arrives after that, you can apply for a warrant of execution, which effectively sends the bailiffs in; a charging order, which stops defendants selling things before paying you; a garnishee order, which freezes their assets; or an attachment of earnings order if you're claiming from an individual, which will ensure that cash is deducted from their salary until they have paid you. Most people who opt for a warrant of execution do consider accepting money in instalments, since this is invariably how the courts will order the payer to pay.
