A delegation of the Victims and Survivors Forum met DUP leader Arlene Foster yesterday to seek assurances that she and her party are committed to addressing the legacy of the past.
The forum also hopes to meet Sinn Féin northern leader Michelle O'Neill in the coming days.
Secretary of State James Brokenshire recently indicated that he plans to launch a consultation on measures contained in the Stormont House Agreement.
The Victims and Survivors Forum say legislation to create those legacy institutions cannot be deferred any longer.
After the meeting, a forum spokesman described the discussions as "candid ".
"The DUP party leader recognised that our membership is diverse but united in seeking delivery of the mechanisms and we offered our support and encouragement to the DUP and all politicians to get legacy issues finally addressed."
Victims Commissioner Judith Thompson, who was also at the Stormont meeting, added: "Victims and survivors will not be the only beneficiaries of delivering mechanisms that will give us access to truth, justice, and acknowledgement or redress the harm caused.
"We need to focus on building a society that we all want to live in and invest in and we can only achieve that by addressing the legacy of the past."
