Depending on your jurisdiction, it could be a simple form processed without a hearing or you may have to do a motion (custom pleadings), appearing in person and telling the court how long it has been since the judgment in question.
I need more info to help you specifically: is it a criminal matter? if so, was it a juvenile matter? a family court matter? is it a financial matter? some records are not expungable some are. Different courts have different rules.
A typical example is removing a record of an old DUI from the public view so that you can get a decent rate on auto insurance and so that prospective employers do not prejudice themselves by looking at that old record and considering you a high risk, because a DUI is technically a "criminal" record.
This is fairly easy to do if it has been a year or two since the DUI and you have a clean driving record since the DUI. There can be no outstanding probation requirements for that, for instance, if you were ordered to diversion (usually traffic school), you must prove to the court that you completed it (school signed off and you filed that paperwork with the court on time.)
One last proviso: you can remove it but it is still there. If you have another case in the same court, the judge can look up the old case.
We'll use our proprietary tools to identify every occurrence of your arrest information online. This involves identifying every site on which your jail record, mugshot photo and/or arrest info appear. Based on the results of this analysis, we will then formulate the best possible approach to get your arrest record and mugshot removed from all the sites that have published it as quickly as possible. Once this is complete we will de-index the links from Google Search, Bing Search and Yahoo Search so that links to the mugshot websites no longer shows up on search results when your name is searched for. This also will also get your arrest photo off Image Search Engines such as Google Images.
More over we use advanced search engine marketing tools to ensure any and all traces of your criminal record and/or arrest mugshot is entirely erased from internet searches like Google and Bing.
Public records are generated in numerous ways – from buying a house, registering to vote, having a phone listing, to filing business records. These records are generated and then stored in a number of places – county auditor offices, recorders offices, secretary of state files, directories and many other places, including, of course, on the internet. A number of states and agencies are working to limit access to, or remove altogether, personal information, such as social security numbers, from these records. The records themselves, however, are public. Documents such as deeds, liens, and court files have always been public; it is the advent of the internet that has generated the ability to search these records from anywhere that has made people so concerned. What used to involve a trip to the courthouse or to a county office now often requires just a few minutes at the computer.
As with most things, there are positives and negatives about having all this information so readily available. People worry about their privacy when records are readily accessible. However, the ability to check on others whom you may want to hire as a contractor, retain as a lawyer or perhaps have a relationship with is of vital importance. Then there is also the ability to see what houses are selling for in your area or in an area you are interested in moving to – seeing the records for oneself helps provide key information and removes some of the dependency on relying on others, such as mortgage brokers, to make important decisions. For documents to not be made public requires legislative authority.
