The British government is to legislate on dealing with the legacy of Troubles murders.
Plans include an amnesty from prosecution for those who co-operate with a panel set up to investigate killings.
It is estimated that more than 1,000 unsolved cases could end up in the system.
The legislation will be introduced in Westminster tomorrow.
It will also include proposals by the UK government for an official history of the Troubles.
Northern Secretary Brandon Lewis said the Northern Ireland Troubles (Legacy and Reconciliation) Bill would put in place an effective investigations and information recovery process, help provide answers for families and deliver on commitments to soldiers who had served in Northern Ireland.
"The current system is failing; it is delivering neither truth nor justice for the vast majority of families. It is letting down victims and veterans alike," he said.
"Every family who lost a loved one, no matter who they were, will be provided with more information than ever before about the circumstances of their death.
"A robust and independent investigations process will be at the heart of this approach, supported by an ambitious and comprehensive oral history programme that will allow people to tell their stories and share their experiences."
But critics believe the plan is the way of offering an amnesty to troops who were involved in killings.
Independent commission to be established
The British government will establish what it calls an Independent Commission for Reconciliation and Information Recovery (ICRIR), run by three commissioners appointed by the Secretary of State.
It will conduct investigations and have the power to compel witnesses.
It will produce reports on killings and produce a "historical record" of what is known in relation to all other deaths that happened during the violence in Northern Ireland.
It will also help coordinate an oral history project to encourage people to share their stories.
The British government says the proposals are a refined version of ones they produced last year.
They provoked outrage amongst victims' groups and were opposed by the Irish Government and most of Northern Ireland’s political parties.
They included plans to end all criminal cases, inquests and civil claims for damages.
The current plans will allow the continuation of any inquest which has reached a substantive hearing within a year of the ICRIR becoming operational, and any civil actions that predated the introduction of the legislation.
The proposals include a plan to commission an official history of the Troubles.
Brandon Lewis said it would be done by independent historians who would be given unprecedented access to UK files.
The Irish Government and most political parties favour an approach adopted at the 2014 Stormont House Agreement.
It would establish an independent Historical Investigations Unit to take on unsolved Troubles cases for families which wished to pursue such a course.
